Piont how using a loop structure array assignment?-CodePudding

 
PointF * point=new PointF [400]. 
for(int i=0; i<400; I++) 
{
//point [I]=PointF (I * 10, I); 
(point [I]). X=I * 10; 
(point [I]) Y=I; 
}

o great god show how using a loop structure array assignment? I feel I didn't send in this assignment, the example of a few basic initialization data points directly in, how do you get this much?

CodePudding user response:

You this looks no problem

reference 1/f, Simple, Soft reply:

you look no problem this

 
Point * Point=new Point [400]; 
for(int i=0; i<100; I++)//399th onto the top position, the last one is the latest data is always on the bottom, 
{
(point [I]). X=array1D [num - pos + I] [j] + 40 + z/W1 * 6; 
(point [I]) Y=H1 - I * H1/400; 

} 

G.D rawCurve (pen point, 2,0.5 f); 
The delete point; 
Point=NULL;

, I'm so circulation assignment drawing painting not to come out, but this assignment alone can draw,

 
PointF point []={PointF (array1D [num - pos + 10] [j] + 40 + W1 * z/6, H1-10 * H1/400), 
PointF (array1D [num - pos + 100] [j] + 40 + W1 * z/6, H1/H1-100 * 400), 
PointF (array1D [num - pos + 200] [j] + 40 + W1 * z/6, H1/H1-200 * 400), 
}; 
G.D rawCurve (pen point, 2,0.5 f);

great god give some directions, this individual assignment and what's the difference between the above circulation assignment? Why couldn't draw graphics

Learn to debug, reducing the complexity,
In terms of your code, not started 100 loop, such as cycle 5 times now, and every change of monitoring parameters, see and you don't have to cycle time have what distinction. Until find out problems,

reference 3 floor truth is right or wrong response:

learn to debug, lower the program complexity,

I a constant 100 direct assignment, looking with a messagebox is 0; See always can't see with interrupt (point [I]). The value of X, the c language pointer array has always been in a daze, did not make clear
